WILLIAM BLRUGGLES, 0F BAYONNE, NEW JERSEY.

DRIER.

To all whom it may concern Be it known that I, WILLIAM B. RUoeLns, a citizen of the United States, residin at Bayonne, in the county of Hudson and i tate of New Jersey, have invented certain new and useful Improvements in Driers, of which the following is a full, clear and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to drier's and with regard to the more specific features to ducts of that style comprising a horizontally disposed, rotatable drum through which a heatmg medium is adapted to flow.

One of the objects of this invention 18 to provide a drier of the above generahstyle that will be practical, comparatively simple in construction and operation, and highly efiicient in use.

Another object of the invention is to provide a drier with the parts thereof so assembledand connected as to permit a ready contraction and expansion ofthe various parts under varying degrees of temperature.

Another obJect of the invention is to provide Within a horizontally disposed, rotatable drum improved means for reventing material, after the same is fe into the drum, from spilling out the front end thereof.

Another object of the invention is to provide the rotatable drum of a drier with means at the rear end thereof to efficiently and rapidly conduct the material after the same is dried to a oint without the drum.

Other objects wil be in part obvious and in art pointed out hereinafter he invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the ap lication of which will be indicated in the ollowing claims.

In the accompanying drawings, wherein is illustrated one of the various possible embodiments of my invention, Figure 1 illustrates a side elevation of a drying apparatus, showing certain parts thereof broken away or in dotted lines for the sake of clearness; Fig. 2 is a plan view of the apparatus shown in Fig. 1; Fig. 3 is a vertical, sectional view of a portion of the same apparatus, showing-the front end of the drum; Fig. 4 is an end view of Fig. 3, the flue being removed Specification of Letters Patent.

taken on the line ww, Fig. 3; Fig. 5 is. a transverse section taken on the line y i lug. 1; Fig. 6 is an end elevation of the rear end of the drum; Fig. 7 is a vertical, sectipnal view of therear of the drum; and Figs. 8, 9 and 10 are detail views of the discharge chute and support.

Referring now to these drawings in detail,

over and around the fine 2 from the source of heat. A space is preferably provided be tween the walls of the flue 2 and the annular extension 5 to permit air to be drawn therethrough into the flue 4. with the heating mediuni to effect a more perfect combustion thereof as it asses through the drum. The partition 5 a so prevents a short circuiting of the heating medium to the fan at the point of connection between the drum and the source of heat. A space is also provided between the end of the flue 2 and the annular ring 6 connecting the fine 4 with the extension 5 to permit a contraction or expansion of the various parts under varying degrees of temperature.

The flue 4 having projecting vanes 4' for stirring the material falling thereon is suported' from the inner walls of the drum 3 by means of suitable connecting links 7 which are also arranged and connected to permit a longitudinal or expanding movement of the parts. A link 7 is rigidly connected with both the drum and the center fine 4 so that the latter may expand in both directions by means of the flexible cnn-' gitudinally disposed relatively to the drum,

and said branches and the inner portions of the links are rigidly connected to said drum 'onto this plate 11 as it is fed into the drum. These flights are.

of 'such shape and so disposed within the drumas to catch the material and carry it upwardly andaround as the drum rotates, so that when it fails, it slides alon the curved surfaces thereof and shoots wel into the drum,thcreby preventing the material from spilling but atthe front end, so ob jectionable with many driers of this general style.

The rearend of the drum is provided with an end plate 10 Figs. 6 and 7, having a central opening in which is mounted a discharge plate 11 of conical formation pro' vided with a plurality of radially disposed partitions 12 so that when the material falls it is carried out through the openin in the plate 10. On the inner surface 0 this plate 10 are provided a plurality of flights or buckets 13 of I Z-shaped cross-section adapted to scoop up the material collecting at the rear end of the discharge drum after the same is dried.

i and 10, maybe placed adjacent plate 11 in front of the discharge opening, to'catch the" By reference to these figures it will appear obvious that as the material is carried up by these buckets and approaches the upper point in the path of travel, it slides out the end thereof onto the plate 11, striking the curved or conical surface, from whence it shoots out the end of the drum. A door 10 in the pla-te 10 permits access to the interior of the drum to clean or repair the same. 'Longitudinally disposed -vanes 14 are placed about the inner wall of the drum to stir up the material as it asses along.

A suitable discharge 0 ute15, Figs. 8, 9

. material as it is discharged from the drum fat through a flaring ring 16, and convey the same to a conveyer if desired.

A plurality of annular rings are disposed about the outer wall of the drum, one of which 1'2 is provided with teeth meshing v with; the teeth of a pinion 17 driven by a suitable motor 18, as shown in Figs. 1 and 2. The otherrings 19 have plane surfaces coacting with suitable supporting rollers 20 beneath the same and horizontally disposed rollers 21 rotating about vertical pivots coacting with the sides of the rings 19 to prevent longitudinal movement of the drum.

Surrounding the point of connection between the fiue 2 and the drum 3 is a stationary hood. 22 having legs 23 resting on amass-r the foundationof the apparatus. 'llhis hood P is provided at one side with a ho per 2&- terminatin in a curved chute wit in the drum, as s ownclearly in Fig. 3, for dlrecting thematerial to be dried onto the rotating flights or buckets 8.

A plurality of openings are provided in the front wall of the hood having hinged doors 25, or the like,-

to permit access to the interior thereof for the purpose of assembling or repairing the parts, and also removing any material that may have collected within the drum.

Connected with the upper part of the I hood is a conduit 26 leading toa suction-fan 27 mounted at any convenient point, as on top'of the furnace 1.' This fan is adapted to withdraw the moisture material as the same is drie and also create a draft through the drum from the discharge opening to draw the heatin medium given off by the discharged at the rear end of the net back to the front end of the drum. Regulating means may be applied if desired, at any honvenient point within the conduit for regulating the amount of draft therethrough.

, An opening 28 is provided at the'rear of the hood 22 above the drum to permit access to the conduit for cleaning or repairing the same.

- The operation of the apparatus is in brief. as follows Assuming a fire to have been built within the furnace and the apparatus to have become well heated, the motor 18 is started to rotate the drum 3 and the suction-fan 27 connected therewith after which the material to be dried is fed into'the hopper 24 at the side of the hood where it falls by gravity onto the flights or buckets 8 about the interior of the rotating drum. It is carried around until it reaches approximately P the highest point of its travel, whence it fall onto the heated flue 4, thence whence it is discharged to the exterior of the drum into the chute 15 if desired.

As many changes could be made in theabove construction and many ap arently widely differentembodiments of this invention could be made withoutdeparting from the scope thereof, it is intended that all matter contained in the above descriptionor shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Y It is also to be understood that the language used in the following claims is in tended to cover all of the-generic and SP8? cific features of the invention herein de scribed and all statements of the sco of the invention, which, as a matter 0 lan guage, might be said to fall the'rebetween.
